Struct gimli::read::UnwindExpression
source · pub struct UnwindExpression<T: ReaderOffset> {
pub offset: T,
pub length: T,
}
Expand description
The location of a DWARF expression within an unwind section.
This is stored as an offset and length within the section instead of as a
Reader
to avoid lifetime issues when reusing UnwindContext
.
§Example
let expression = unwind_expression.get(&eh_frame)?;
let mut evaluation = expression.evaluation(fde.cie().encoding());
let mut result = evaluation.evaluate()?;
loop {
match result {
EvaluationResult::Complete => break,
// Provide information to the evaluation.
_ => { unimplemented!()}
}
}
let value = evaluation.value_result();
Fields§
§offset: T
The offset of the expression within the section.
length: T
The length of the expression.
Implementations§
source§impl<T: ReaderOffset> UnwindExpression<T>
impl<T: ReaderOffset> UnwindExpression<T>
sourcepub fn get<R, S>(&self, section: &S) -> Result<Expression<R>>where
R: Reader<Offset = T>,
S: UnwindSection<R>,
pub fn get<R, S>(&self, section: &S) -> Result<Expression<R>>where
R: Reader<Offset = T>,
S: UnwindSection<R>,
Get the expression from the section.
The offset and length were previously validated when the
UnwindExpression
was created, so this should not fail.
